Generally speaking, the gameplay hasn’t changed: if your difficulty settings allow it, you mouse over crime scenes until your cursor changes from a blue arrow to a green one, indicating that an area requires further scrutiny. When you are brought closer to inspect the items, the “Tools” tab automatically becomes active, and while that seems like a minor detail, it saves you quite a bit of clicking. However, the gameplay is slightly more sophisticated in that lab work has been simplified, while the investigation of evidence has been intensified.
